A feedwater heater in a vapor power plant operates at steady state with liquid water entering at inlet 1 with T₁ = 45°C and p₁ = 9.0 bar. Water vapor at T₂ = 320°C and P2 = 9.0 bar enters at inlet 2. Saturated liquid water exits with a pressure of p3 = 9.0 bar. Ignore heat transfer with the surroundings and all kinetic and potential energy effects. The mass flow rate of the liquid entering at inlet 1 is 3.2 × 105 kg/h. Determine the temperature at the exit, T3, in °C, and the mass flow rate at inlet 2, in kg/h.

at inlet 1 with T₁ = Water vapor at T2₂ = A feedwater heater in a vapor power plant operates at steady state with liquid water entering 45°℃ and p₁ = 9.0 bar. 320°C and p₂ = 320°C and P2 = 9.0 bar enters at inlet 2. Saturated liquid water exits with a pressure of p3 = 9.0 bar. Ignore heat transfer with the surroundings and all kinetic and potential energy effects. The mass flow rate of the liquid entering at inlet 1 is 3.2 × 105 kg/h. Determine the temperature at the exit, T3, in °C, and the mass flow rate at inlet 2, in kg/h.
